Paul Urbach graduated in 1981 at the University of Groningen, the Netherlands, and completed in 1986 a Ph.D. thesis at the same university on the optimization of hydrodynamic propulsion. In 1986, he joined Philips Research Laboratory in Eindhoven, the Netherlands. During 1980, he spend four months in Signetics Research Laboratory in Sunnyvale, California, the USA, where he worked on optical lithography. In 1994, he became a principal scientist at Philips Research Laboratory. In 2000, he became a part-time professor in diffraction optics at Delft University of Technology (TUDelft), the Netherlands. Since January 2008, he is a full professor and the head of the Optics Research Group of TUDelft.
